I have been participating in the sport of Jam Skating (fancy rollerskating) for the last 6 years at my local roller rink. Since the start I have been going through wheels, bearings, boots, and trucks/plates, not just because they broke but because they wore out. I have seen skate wheel regroovers before but I don't need need one if I have a metal lathe that is more precise any way.
So I set out to design a tool that skate wheels attach to and can be mounted on my lathe between centers.
**Before you attempt this project on the metal lathe you should be comfortable with turning cuts, facing cuts, and single point threading. You should also be familiar with feeds and speeds appropriate for your lathe.**
Step 1: Designing the Arbor
•Mount between centers
•Must be very accurate and repeatable
•Must regroove all skate wheels
My sketch shows the mounting arbor where the counter bores of the wheel seat, it also show the taper nut that centers the wheel on the arbor.
